getConversationList
(Android/iOS and macOS/Windows) to get the conversation list. This API pulls locally cached conversations. If any server conversation is updated, the SDK will automatically sync the update and notify you in the V2TIMConversationListener
callback.V2TIMConversation
objects. SDK sorts conversations according to the following rules:orderKey
by default. The greater the orderKey
value of a conversation, the higher position the conversation is in the list. The orderKey
field is an integer that increases as the conversation is activated when a message is sent/received, a draft is set, or the conversation is pinned to the top.lastMessage
-> timestamp
of the conversation by default. The greater the timestamp
value, the higher the position of the conversation is in the list.lastMessage
of a conversation may be empty, such as when the messages in the conversation are cleared. If you use the SDK earlier than v5.5.892, you need to handle the exception when sorting the conversations by lastMessage
. We recommend you upgrade the SDK to v5.5.892 or later and sort the conversations by orderKey
